“Hidden” Dynamics in Relativistic Kinematics

It is shown using the Fizeau and Doppler effects that if under concrete conditions of experiments, interaction between light (photons) and the fields or matter is taken into account, the experimentally proven kinematics formulas of special relativity can be derived in the framework of three‐dimensional Euclidean space with time independent of the spatial coordinates. A formula for the transformation of the energy of a photon from one inertial (in the sense of Galileo) frame to another has been derived.
